The Bitcoin community is currently debating the relevance of the cryptocurrency's four-year cycle as market dynamics evolve. Critics argue that the cycle may not extend to 2026, citing $57 billion in ETF inflows as a transformative factor. However, proponents maintain that the cycle remains intact, noting historical coincidences such as Bitcoin's local bottom on November 21, 2025, at $80,524, mirroring the previous cycle's low on the same date in 2022 at $15,460. Attention is now focused on January 2026, with a U.S. crypto market structure bill set for a hearing on January 15. This legislative event is anticipated to be a pivotal moment for Bitcoin's current cycle, potentially influencing its trajectory.
